Has anyone noticed the new vhf low band "England Wide" analogue network set up by Ambitalk (Maxxwave)?

The frequencies they have are as follows (25 kHz Bandwidth)...

TX: 66.7000 MHzRX: 67.9000 MHz

TX: 66.2250 MHzRX: 67.4250 MHz

TX: 66.4500 MHzRX: 67.6500 MHz

TX: 64.8375 MHzRX: 64.8375 MHz

TX: 66.3250 MHzRX: 67.5250 MHz

TX: 66.8375 MHzRX: 66.8375 MHz

TX: 66.5250 MHzRX: 67.7250 MHz

TX: 66.4000 MHzRX: 67.6000 MHz

TX: 64.8125 MHzRX: 64.8125 MHz

TX: 66.6250 MHzRX: 67.8250 MHz

TX: 66.8125 MHzRX: 66.8125 MHz

This appears to be an "England Wide" network. It also appears to be wholly analogue as they dont seem to like DMR or dPMR they say on their site...

Ambitalk is really simple to use. Just press the button and talk. Your audio will automatically be routed through our advanced network of radio masts, microwave links and switching hubs to arrive at the other end without any appreciable delay that is present on "DMR" or "dPMR" digital systems. Crystal clear, distortion free, superb coverage. It really is that simple.

I just read on another site that 66.21875MHz is The Ambitalk control channel for East Yorkshire, and that the signal quote "goes for miles". Quite interesting as thats a simplex one. I've had a quick scan about 66MHz around here and not picked anything up so far.

The wiki entry https://en.wikipedia.org/wiki/Ambitalk reveals more interesting stuff. It would seem that digital on the lower bands isn't very effective because of the strange propagation the lower bands suffer from, hence why analogue would seem to be the only mode that would be workable. Fading and delayed reflections would make digital very difficult to implement, so they've turned a negative into a positive, which is neat. It seems to be a re-invention using established technology in a very undersized band. I guess the mobile repeater option will be UHF, and again, simple too implement. The real key to the success I hope they get is the fact that low band, and this is ten meg lower than we've really been used to, is almost an unwanted band due to antenna sizes - but if they are only interested in vehicles as the primary target, then the long whips aren't that much of a problem.

OFCOM have a price checker on their site to give you an idea of the price for technically assigned licences and band one, the home of this new system is the cheapest in terms of pounds per area. It's still a lot for country wide coverage but nowhere near the mega money for VHF high band, which is where wide area interest and frequency shortages seem to be.

Scanned those freqs tonight and nothing at all. On Google streetview I see a re-painted warehouse with no company sign on it on it for that postcode location. I am actually not that far from the industrial estate where they are supposed to be located so I could go have a look sometime. There is an established ham repeater site not far from that location but the picture of the mast they show is rather different.
